Bolivia is a South American landlocked country; known as the most isolated country on the continent, around 60% of its population comprises Indigenous Peoples.
The nation is also home to 25 species of New-World monkeys, though just two are endemic to it: the Beni titi monkey (Plecturocebus modestus) and the Ollala Brothers’ titi (Plecturocebus olallae).
The latter, an endangered species, is known for its energy-conserving behavior—during drier seasons, it will move around less to get food, and, instead of scouring for particular fruits as it usually does, it will settle for consuming more common foods, such as seeds and fungi.
This efficient dietetic strategy helps the Ollala Brothers’ titi to suitably live in the Llanos de Moxos wetland of the Amazon Rainforest.
Other common monkey species in Bolivia include the saddleback tamarin (Leontocebus fuscicollis), the Bolivian red howler monkey (Alouatta sara), and the black-headed night monkey (Aotus nigriceps).
Species Name: Leontocebus leucogenys Native Countries: Peru,Bolivia,Colombia,Brazil,Ecuador
The Andean saddle tamarin, also known as the saddleback tamarin (formerly known as the brown-mantled tamarin), is a New World monkey species. Andean saddleback monkeys are considered "phyletic dwarfs," meaning their small size is related to their evolutionary development.
Species Name: Aotus azarae Native Countries: Bolivia,Paraguay,Brazil,Peru,Argentina
Azara's night monkeys, also known as southern night monkeys and Azara's owl monkeys, are native to the Gran Chaco region of South America, a vast area with many different ecosystems, from savannas to grasslands to dry spiny forests and gallery forests. Genetic testing has shown that the males of this species mated pairs are the fathers of the babies they care for.
Species Name: Saimiri ustus Native Countries: Brazil,Bolivia
The bare-eared squirrel monkey also called the golden-backed squirrel monkey, is a subspecies of the Saimiri sciureus group native to the tropical forests and jungles of South and Central America. The bare-eared squirrel monkey differs from other species because it does not have ear tufts.
Species Name: Alouatta caraya Native Countries: Bolivia,Brazil,Paraguay,Argentina
Alouatta caraya is found in the tropical rain forests of central South America, extending through eastern Bolivia, Paraguay, southern Brazil, and northern Argentina. Alouatta Caraya monkeys are sexually dimorphic, with males weighing an average of 6.7 kg and females an average of 4.4 kg.
Species Name: Ateles paniscus Native Countries: Brazil,French Guiana,Guyana,Peru,Bolivia
Ateles paniscus, the black spider monkey, is one of three sub-species of spider monkeys. Aside from the face, feet, and hands, they are covered in jet-black hair longer than a typical primate. Of all the Ateles species, Ateles paniscus is the largest.
Species Name: Saimiri boliviensis Native Countries: Bolivia,Brazil,Peru
The black-capped squirrel monkey is a New-World primate species endemic to the upper Amazon basin in Bolivia, eastern Peru, and western Brazil. Primarily, black-capped squirrel monkeys are arboreal and found in native and plantation forests and some managed areas close to running water.
Species Name: Mico melanurus Native Countries: Brazil,Bolivia,Paraguay
The black-tailed marmoset is a New-World monkey species native to central South America. It is distributed from south-central Amazonia in Brazil to the Chaco far north of Paraguay. Black-tailed marmosets are arboreal and diurnal, using their claws for tree climbing.
Species Name: Callimico goeldii Native Countries: Bolivia,Brazil,Colombia,Ecuador,Peru
Goeldi marmoset or Goeldi monkey is a small South American New-World monkey living in the upper Amazon basin region of Brazil, Bolivia, Ecuador, Colombia, and Peru. Goeldi marmosets generally stay less than 5 meters from the forest floor, moving to higher elevations for fruit.
Species Name: Sapajus cay Native Countries: Paraguay,Bolivia,Argentina,Brazil
The Azaras capuchin or hooded capuchin (Sapajus cay) is a robust capuchin species. It is found in northern Argentina, southeastern Bolivia, eastern Paraguay, and Brazil. Its habitat consists of humid, subtropical, semi-deciduous, gallery forests and forests in the Pantanales.
Species Name: Cebus albifrons Native Countries: Bolivia,Brazil,Colombia,Venezuela,Ecuador,Peru,Trinidad and Tobago
Humboldt's white capuchins, also known as white-fronted capuchins, are a species of New-World monkeys and one of the smallest capuchin groups. Humboldt’s squirrel monkeys are usually led by a dominant male and female.
Species Name: Lagothrix lagothricha Native Countries: Colombia,Ecuador,Peru,Bolivia,Brazil,Venezuela
Humboldt's woolly monkey, common woolly monkey, or brown woolly monkey (Lagothrix lagothricha) is a woolly monkey endemic to South America. Humboldt's woolly monkeys can show subtle mood swings and intentions with various facial expressions.
Species Name: Ateles chamek Native Countries: Peru,Brazil,Bolivia
Peruvian spider monkeys, like other Ateles species, have a prehensile tail that can be used to facilitate brachiation. Typically, Peruvian spider monkeys have completely black fur and complexions, unlike the lighter red-faced black spider monkey.
Species Name: Cebuella pygmaea Native Countries: Bolivia,Brazil,Colombia,Ecuador,Peru
The pygmy marmoset (smallest monkey), genus Cebuella, is a small genus of New-World monkeys endemic to the tropical rainforests of the western Amazon Basin in South America. Pygmy marmosets are also highly territorial, using scent glands to mark territories of up to 100 hectares.
